WESTMINSTER, Md. — With injuries continuing to hinder the training camp roster, John Harbaugh and the Ravens are probably thinking they cannot get away from McDaniel College fast enough and back to the cozy confines of 1 Winning Drive as the injury list continues to grow daily, particularly on the offensive line.

Right tackle Oniel Cousins was carted off the field after suffering from a headache on Wednesday morning. Cousins, already filling in for the injured Jared Gaither (back tear), appeared to be laboring earlier in practice and stood on the sidelines for a considerable time before leaving the field. The training staff will test Cousins for a possible concussion.

Tony Moll filled in on the right side in Cousins’ absence while Chris Chester continues to handle the center position in place of Matt Birk (neck). Other linemen missing practice included Stefan Rodgers (arm) and Daniel Sanders (arm).

It was an “over-30 club” day in Westminster, meaning the likes of Ray Lewis and Derrick Mason were given the day off. With veterans receiving a respite and so many others not practicing, fans could be forgiven if they didn’t recognize all players running with the starting units at times.

New absences from practice included fullback Le’Ron McClain (back/thigh) and linebackers Tavares Gooden (neck) and Prescott Burgess (undisclosed). McClain appeared to be dealing with an upper thigh issue over the last few days, even having the hip and thigh region wrapped during Saturday afternoon’s practice. The starting fullback was in street clothes, walking with a limp during the morning session, but the injury is not believed to be serious.

Gooden continues to deal with neck spasms after sustaining an awkward hit to the neck in the preseason opener. Despite practicing the last two days, the team will use caution the rest of the week in hopes that Gooden will be able to play against the Redskins on Saturday.

“[The neck] just keeps tightening back up on him,” Harbaugh said. “We need to just sit him down and settle him down.”

Gooden’s health clouds what has been an intriguing competition at inside linebacker after Jameel McClain lost his stronghold at the position with a poor performance in the preseason opener. McClain has received more work at the “Sam” outside linebacker with the second unit this week. Harbaugh hopes to get extended looks at all three with the starting defense over the final three preseason games.

“We’ll kind of move those guys around the next two weeks, and we’ll know where we’re at.”

In addition to the “over-30″ club—which includes Lewis, Mason, Birk, Todd Heap, Travis Fisher, Trevor Pryce, and Kelly Gregg (Ed Reed and Brendon Ayanbadejo are still on the PUP list)—defensive tackle Brandon McKinney (knee), tight end Davon Drew (hamstring), and defensive back Marcus Paschal (leg) joined the aforementioned players as non-participants in the morning practice.

1:40 p.m. — Both Billy Cundiff and Shayne Graham missed from 45 yards on Wednesday morning. Cundiff pulled his attempt wide left while Graham was wide right on his try.

Each kicker connected from 19, 40, and 51 yards as both continue to produce similar results day in and day out in Westminster.

12:45 p.m. — With Thursday being the last two-a-day of the summer, coaches and players are laboring through the final workouts in Westminster and toward the remainder of the preseason schedule. John Harbaugh has been pleased with the team’s work during camp, evidenced by his cancellation of three practices (one on Saturday and two on Sunday) over the last week.

“You get to this point and it’s time to [go],” Harbaugh said. “You’re looking into the next phase of camp. Going into this practice [on Tuesday morning], we wanted to make sure that we have five good practices before we leave here, to make the most of it, and we did a good job today.”

The Ravens will conduct a walk-through on Friday before breaking camp and continuing their preseason preparation at their practice complex in Owings Mills.

12:35 p.m. — As mentioned yesterday, rookie David Reed has struggled to catch the ball consistently after a strong beginning in Westminster. Reed, a fifth-round pick in April, was expected to battle for the fifth receiver job but has fallen out of contention with Demetrius Williams having such a strong—and injury-free—training camp.

With three preseason games remaining, Reed will need a strong showing at receiver and on special teams to avoid being cut or stashed away on the practice squad—or Injured Reserve with a mysterious injury.

“You want consistency,” Harbaugh said about the young receivers following Tuesday’s practice. “For whatever reason, we dropped a lot of balls out here today. I thought the quarterbacks were just a little more in rhythm with their throws [and] a little quicker versus the pressure, which is what we want, and maybe it caught the receivers a little bit off guard.”

Hale acknowledges he has struggled to catch the football in camp, something he has not experienced previously in his career.

12:20 p.m. — Cornerback Chris Carr and receiver Mark Clayton suited up to practice but were limited participants throughout the morning session. Carr has taken part in individual drills the last two days but continues to sit out team portions of practice as he continues to recover from a left hamstring injury sustained on Aug. 7.

With Carr sitting out 11-on-11 drills and the 30-year-old Travis Fisher not practicing, Fabian Washington and Cary Williams were the cornerbacks with the first defense.

Clayton had his right ankle taped before walking out to practice, but the receiver stood on the sideline without a helmet and gloves for much of practice. Demetrius Williams and Donte’ Stallworth split reps at receiver opposite of Anquan Boldin with Clayton out and Mason receiving the day off.
